A). I would start at $100 through $200. since the range doesn't start until $110 there is no reason to show the numbers 0-90.

b). I would then go up by 10 on each interval. going up by 10 can easily be graphed and accurate.

What is the point slope form of the line with slope 2/5 that passes through the point (−4, −7) ?
Sidana [21]

Answer:

The point slope form of that graph would be D) y + 7 = 2/5(x + 4)

Step-by-step explanation:

We know this by plugging into the point-slope form of the equation, which is listed below.

y - y1 = m(x - x1)

y - -7 = 2/5(x - -4)

y + 7 = 2/5(x + 4)

Someone help me out on these 2 geometry questions, ASAP!!!<br> “Complete the proofs”
vodomira [7]

<u>Question 11</u>

1) \overline{BA} \cong \overline{FA}, \angle 1 \cong \angle 2 (given)

2) \angle A \cong \angle A (reflexive property)

3) \triangle AEB \cong \triangle ACF (ASA)

4) \overline{AC} \cong \overline{AE} (CPCTC)

<u>Question 12</u>

1) Isosceles \triangle ACD with \overline{AC} \cong \overline{AD}, \overline{BC} \cong \overline{ED} (given)

2) \angle ACD \cong \angle ADC (angles opposite congruent sides in a triangle are congruent)

3) \angle ACB and \angle ACD are supplementary. \angle ADC and \angle ADE are supplementary (angles that form a linear pair are supplementary)

4) \angle ACB \cong \angle ADE (supplements of congruent angles are congruent)

5) \triangle ABC \cong \triangle AED (SAS)

6) \overline{AB} \cong \overline{AE} (CPCTC)

7) \triangle ABE is an isosceles triangle (a triangle with two congruent sides is isosceles)

<em>Note: I changed the names of the segments in Question 11 because of the word filter.</em>

Find the value of the cot 10° using your calculator.
Galina-37 [17]
The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.

Are they correct? Why or why not? answer correctly thank you 10 points.
Kitty [74]

Answer:

No.

Step-by-step explanation:

the system of equations provided in the condition consists of two linear equations in slope-interception form. The slope of the 1st equation is equal to the slope of 2d equation. It means, the lines are parallel. In other words, no solution of this system, they are not correct.

Answer: no.
